PCT No. PCT/EP80/00021 Sec. 371 Date Dec. 10, 1980 Sec. 102(e) Date Dec. 8, 1980 PCT Filed Apr. 10, 1980 PCT Pub. No. WO80/02198 PCT Pub. Date Oct. 16, 1980.Device for liquid flow cytophotometer including a device for hydrodynamic focussing (4,6) of a cell- or particle-suspension towards a measuring area, and an optical excitation-and detection-system (9), preferentially based on oil immersion optics, characterized by the focussing device being formed at or in relation to the system's optical axis-rotating nozzle assembly (1) directed towards a surface (7) which is open in relation to the surrounding atmosphere and situated on the optics (9), forming the optics' measuring area, thus supplying a laminar liquid flow of the above-mentioned suspension.
